问题 Is there any way I can add XAML controls to my WP 8.1 Silverlight app? I'd like to use progress rings and toggle switches but it seems like Silverlight doesn't have them. How can I add them? Adding a "using Windows.UI.Xaml.Controls" reference doesn't work by the way. 回答1: Windows.UI.Xaml.Controls is Windows Phone 8.1 Runtime only (or better known as Universal App). If you don't like the controls already in Silverlight, Microsoft has release a extended control kit all "Windows Phone Toolkit".

问题 Ok this has been bugging me and I haven't really found any kind of definitive answer as the the reason/cause of the difference between Color & SolidColorBrush so I'm wondering if someone can educate me on this. I already know the differences in usage, like for example I can use a SolidColorBrush in a dependency like if I say; <SolidColorBrush x:Key="BlahBrush" Color="#FFFFFFFF"/> <Border Background="{StaticResource BlahBrush}"/> but then say I throw the same resource in an EasingColorKeyFrame
